Abstract
The invention relates to the field of molding sand casting, in particular to paint used for casting. The paint is characterized by comprising the following ingredients in parts by mass: 10 to 20 parts of phenolic resin, 15 to 25 parts of rosin, 40 to 50 parts of carriers, 5 to 8 parts of zircon powder, 2 to 4 parts of carbon fiber, 5 to 6 parts of additives, 10 to 15 parts of ceramic powder and 2 to 5 parts of fentin hydroxide. The paint has sufficient rapid-heating-resistant performance and high-temperature stability, and can bear the thermal stress action during high-temperature intense heating; coatings do not crack or peel off; and good suspension stability and good bondability are achieved.
Description
Technical field:
The present invention relates to casting field, relate to a kind of coating casting use in particular.
Background technology:
The coating of sand casting, mainly for shielding the interphase interaction of sand mold and metal liquid, density fireproof coating is formed under cast temperature, placing metal liquid penetrates in sand mold, simultaneously because the material of sand mold at high temperature decomposes generation gas, coating can prevent from entering in metal liquid, affects the surface smoothness of foundry goods.Conventional is cold coating at present, because be suspension liquid, and suspension is low, does not stop to stir and could brush evenly, otherwise can not form fine and close coating during use.Under vacuum conditions in integral cast one-shot forming gate manufacturing process, use special coating to arrive Expected Results with regard to needing.
Summary of the invention:
Technical problem to be solved by this invention is that overcoming existing technological deficiency provides a kind of coating casting use.
Technical problem to be solved by this invention adopts following technical scheme to realize:
Cast a coating for use, it is characterized in that being made up of the raw material of following masses number: 10-20 part phenolic resins, 15-25 part rosin, 40-50 part carrier, 5-8 part zirconium English powder, 2-4 part carbon fiber, 5-6 part additive, 10-15 part ceramic powder, 2-5 part triphenyl tin hydroxide.
Further, described carrier is the one of ethanol, methyl alcohol or isopropyl alcohol.
Further, described carrier is ethanol, and described ethanol mass fraction is greater than 95%, and boiling point is 70 DEG C, and density is 0.80g/cm
3, flash-point is 12 DEG C.
Further, described additive comprises the component of following weight portion: 1-2 part anticorrisive agent, 2-3 part wetting agent, 1-2 part defoamer, 0.5-1 part oxidant.
Further, described coating using method is the thickness that primary coating reaches suitable, and thickness of coating layer is between 1-1.5mm.
The present invention has enough emergency heat and cooling property resistances and high-temperature stability, can stand high temperature causus time thermal stress effect, coating does not ftracture, do not peel off, and has good suspension stability and cohesiveness.
Detailed description of the invention:
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with specific embodiment, setting forth the present invention further.
